All Door Lock

The all door lock feature allows the following actions:
^ The BCM locks all of the doors when you press LOCK 1 time with all of the doors closed.
^ The BCM delays door locking when the driver's door is open and the key is removed from the ignition switch.
This action enables the last door locking feature. If you press LOCK on a door lock switch, the BCM sounds the chime 3 times in order to indicate that the last door closed locking is active. The BCM locks all of the doors 5 seconds after all of the doors are closed.
If you press LOCK 2 times, you will bypass the last door closed locking feature. The BCM locks all of the doors immediately, even if a door is still open.
^ The BCM does not lock the doors if the driver's door is open and the key is fully inserted in the ignition switch. This enables the lockout prevention feature.

If you press LOCK on either door switch, a ground signal is sent to the BCM through CKT 195. The BCM evaluates the last door locking and lockout prevention features in order to determine when it is appropriate to lock the doors. At the appropriate time, the BCM applies voltage in CKT 295 for 315-385 ms. This action energizes all of the door actuators. The energized door actuators lock all of the doors.
